[dev] "range in overlapped buffers" in range filter

[Manlio Perillo]

I'm testing range support with a WSGI application that reads a file in 
chunk, writing each chunk to the client.
http://hg.mperillo.ath.cx/nginx/mod_wsgi/file/tip/examples/nginx-file.py

I get this error:
range in overlapped buffers



Does this means that range filter only works if the application uses one 
nginx buffer?



Thanks  Manlio Perillo
